Jacoco is giving me this error when trying to test my web service (I get it with any maven goal that includes the test phase):

Just to be clear, I am not using StringUtils anywhere in my code, not even in my test code. My project builds and runs fine without it, if tests are skipped.
I've googled maven issues, jacoco issues, surefire issues, and tried all solutions I came across.
Here is what I tried:
- Clean build, also deleting the whole target directory manually
- Adding several different dependencies containing StringUtils to the pom (including the original commons-lang-2.6.jar and the new commons-lang3 library)
- Deleting my .m2/repository/org/apache/maven directory to redownload all repository libraries
- Comparing with my other projects that use similar test cases to find any possible difference that might cause this
- Using different versions of surefire, failsafe, and surefire-report plugins
- Adding
<skipTests>true</skipTests>to both surefire and failsafe plugin configurations in the pom (some similar issues I read happened because test cases were being run twice) - Excluding various output directories using
<exclude>tag in jacoco plugin configuration - Altering the source and target JDK versions in the maven compiler plugin configuration
- Inserting the StringUtils.class directly into the jacoco pom in the appropriate directory matching the missing class name and package
- Using different versions of the jacoco plugin
- Installing and using a different version of Maven (tried both 3.1.1 and 3.3.9)
- Switching to cobertura (I get a very similar error that differs only in the class it says is missing - org/apache/commons/lang/SystemUtils, rather than StringUtils)
I've been pulling my hair out over this for a whole day. I was able to have someone else test it and it worked fine on their system. I then copied their target directory onto my machine and was able to execute Sonar code analysis against the successful build results (jacoco.exec and the checked in code).
My question is, what is messed up on my system that is causing this?
I am running Windows 7 64-bit on a HP EliteDesk. Here is my pom.xml:

My test cases aren't anything special, they basically just send a sample POST request to each of the endpoints and verify that a result comes back.
Here is an example test case:
private CustomResponse executePostRequest()
{
MyPojo data = new MyPojo();
data.setId(0);
data.setRequestType("sometype");
data.setSomeField("value");
data.setSomeOtherField(5);
return target.path(endpoint).request().post(Entity.json(data), CustomResponse.class);
}
@Test
public void testEndpoint()
{
CustomResponse response = executePostRequest();
assertTrue( response.getCode() == 200 );
}
I'll be happy to post any other settings or whatever you might want to know about my system.
UPDATE: I just found out about jHades which is a tool to help you identify conflicting Jar resources when you run into jar-hell scenarios like this. I haven't tried it yet, but I plan to and will update the results here if it produces anything.
